You can't even understand what I'm asking, that's why you can't explain it. This has everything to do with your misunderstanding. In the above example an object (let's say an asteroid) will come crashing into earth unless
it works out extremely complicated math formulas that not only actually EXERTS a completely equal but a totally opposite force in the opposing direction to negate the force that it already has. Earth's gravity doesn't somehow grab hold of that object and make it equal to the speed at which it orbits the sun allowing it to land perfect. So if an object like a satellite has an on board computer they can do the math sure, but then they need many directional rockets to be able to steer in space (remember there;s no air to steer through)that would not only somehow be able to negate speeds so fast (that we can't even go btw), but also do this within seconds because when your traveling that fast, the ground comes up pretty quick but there was a 27 fucking minute delay between communications.
Now can you see someone at the controls here on earth saying - ah looks like we need to adjust a little left - and then 27 minutes later the satellite should have gotten the message but it's not there anymore - hmm wonder where it went - oh idk - maybe smashing into your comet? There is a saying, just because you fly it up a flag pole, doesn't mean you have to salute it.
Do you know what that means , that means if the story is shit, dont waste your time with it. I'm really beginning to think this story is a honey trap and they really wanted to see how many flies they could catch.
so you just outright refuse to educate yourself on this topic?
" Is Rosetta pre-programmed or are commands sent from the ground?
Rosetta is operated from the ground. It was impossible to programme manoeuvres for the whole mission before the launch because this would have entailed adjustments at each stage of the journey. Ground commands are sent periodically to readjust the spacecraft’s trajectory. These take up to 50 minutes to reach the spacecraft, when it is farthest from the Earth.
How does the spacecraft deal with this long time lag?
To compensate for the delay, Rosetta is provided with built-in intelligence to look after itself. This is done by its on-board computers, whose tasks include data management and attitude and orbit control. In the event of problems during the lengthy cruise, experts added backup systems to ensure that the spacecraft could remain operational during critical mission phases. For example, to avoid losing power, the spacecraft automatically positions itself with the solar panels facing the Sun. "
who knew that years of design and engineering would allow something to be smarter than your $50 android phone?!!?
